Overview:

Q28QD040C00F is a high performance QSFP28 transceiver module for 100 Gigabit Ethernet data links over a single mode fibre pair. The maximum reach is 40km. The four transmitters are cooled 1310nm LAN-WDM Electro-Absorption Modulated Lasers (EML) generating four optical 25Gbps output signals, which are multiplexed together at the optical output port. The four receivers are avalanche photodiodes (APD) which detect (after optical de-multiplexing) 4´ 25Gbps optical input signals. This transceiver module is compliant with the QSFP28 Multisource Agreement (MSA) and hot pluggable.

Features:

  • QSFP28 Multi-Source Agreement compliant
  • Hot pluggable QSFP28 footprint
  • Supports 103.125 Gbps Data Rate
  • Dual LC Optical Connector
  • 4x 25.781Gbps Serial Electrical Interface (CEI-28G-VSR)
  • 4x cooled 1310nm LAN-WDM EML Transmitters
  • 4x APD Receivers
  • Up to 40km/30km (with/without FEC) Point-to-Point Transmission on Single Mode Fibre
  • Operating temperature range 0°C to 70°C
  • Power Dissipation < 4.5W
  • Single +3.3V Power Supply

Standard:

  • 100GBASE-ER4 Lite

Benefits:

  • Compatible with all the major brands
  • Fits every QSFP28 ports on the market

Limitations:

  • risk for the APD when overloading the Receiver

Compatibility matrix:

Note 1: FEC must be used irrespective of distance / Note 2: Operation w/o FEC is possible for distances up to 30km. 40km operation only possible w/ FEC operation
